[Assessing COPD-associated morbidity: factors of prognosis].

Background And Objective: Forced respiratory volume in first second spirometry is currently used to diagnose chronic obstructive pulmonary disease. However, this technique does not always provide a reliable short-term prognosis, especially in patients with associated morbidity. We propose that specific health-related quality of life questionnaires are a better tool to estimate the prognosis of chronic obstructive pulmonary disease.
